A FORTRAN Subroutine to Evaluate Spherical Bessel Functions of the First, Second, and Third Kinds for Complex Arguments.

Abstract

To determine analytically the acoustic scattering from absorbing spheres it is necessary to evaluate spherical Bessel functions of the first, second, and third kinds for complex arguments, covering a range of integer orders from zero to a value approximately equal to the absolute value of the argument. A double-precision (G-format) FORTRAN subroutine, CSPJYD, has been written for the VAX-750 that will generate tables.
